Abstract

This study discusses a single-phase half-wave uncontrolled rectifier using a three-phase AC generator. The rectification process is simulated using Proteus software, which displays a sinusoidal waveform to identify the behavior of the single-phase half-wave rectifier. The system uses a three-phase AC generator as the load, which is connected to the half-wave rectifier circuit. A half-wave rectifier is a system that uses a single diode block—either one diode or multiple diodes in parallel—to convert alternating current (AC) voltage into direct current (DC) voltage. Its operation is based on the unidirectional characteristic of diodes, allowing current to flow in only one direction. This type of rectifier is called “half-wave” because it only passes the positive half cycle of the AC signal. A generator is a device that converts mechanical energy into electrical energy, which can be driven by wind turbines, water turbines, or steam turbines. These turbines rotate the generator shaft to produce electricity through the coil inside the generator. An alternator is a type of generator that produces AC output voltage. As most current power systems use AC, alternators play a central role in power generation. Their size varies depending on the load capacity, especially in large-scale power plants.
